ZOOLOGY.

“ Besides the above insects, a very minute spider was seen in abundance, 
running over the plants, and on the ground, and leaping when alarmed. I 
have seen only a single specimen, which was so much injured that I cannot 
be positive as to the genus, but from its jumping, it most probably is a spe- 
cies of Salticus, Lath. (Attus Walck). I, at first, took it for a variety of Aranea 
rujipes, (O. Fabr. 206) ; but as the characters glaberrima, pedibus testaceis, do not 
agree with it, it may be considered as a new species. 
Melmllensis. S. black ; legs piceous, hairy ; abdomen hairy. 
Length of the body about 1| lines. 
This was the only species which Captain Sabine observed on the island.”

INVERTEBRATE ANIMALS. 
The Genera, into which the several species of invertebrate animals have 
been distributed, are those of the system of the Chevalier de Lamarck, 
Histoire Naturelle des Animausc sans Verthbres. 
The object which has been chiefly attempted in the present account, has 
been to identify those species which have been previously described, and 
to compare the individuals with the descriptions of original observers, refer- 
ring to the works in which they are noticed, and marking any differences 
which may have appeared in the comparison ; and to furnish descriptions 
of the previously unknown species, sufficiently extended to enable the several 
systematic writers to arrange them in Genera according to their respective 
views and systems.
